I LOVE IT! It was adorable.

What a great story to rear! I loved the lil AU aspect but man this was great. I have to admit how sulley talked was one of the best parts! So hilarious. Great job.

AWESOME!

I've always wanted to go to Comic Con and cos lay as well so seeing Sulley do the same makes me a happy geek

Loved this story so much, it was to cute :)

loved it

This story was very good. I hate to say it, but normally I wouldn't have even clicked this based on the description (even though I like Thor/Avengers and it sounds creative enough, it seems like it might be weird). I only clicked it because you wrote it and I liked your other stuff.
HOWEVER, I'm VERY glad that I did click it. It was very well written, and the ending actually made me feel a bit sad for what could have been.
I never even thought about the fact that Sulley was able to make Boo's costume so quickly haha. That's actually pretty funny, and, like you, I doubt that Mike would have helped at all. He was very against Boo in the beginning. With that in mind, I could easily see Sulley using that skill to make costumes (obviously amazing costumes) for himself.
The idea of Sulley meeting a costumed Randall (whose costume fit Sulley's theme too!) was pretty cute. And the picture *sad* was such a cute idea. If only either of them had been a bit different, they might have seen a potential friendship instead of reasons to be embarrassed/distrustful.
I am of the opinion that Randall could have turned out quite a bit differently if he could have found a real friend. Oh well :(
But yeah, Sulley finding the picture was very cute :3 Too bad there isn't really anything that he could do about it at that point in the story.

So yeah, good story, I liked it a lot! I just love your writing skills and how well you manage to capture the characters and the emotions.

Aaaawww that was fantastic! :) Very cute little story C:

Fantastic writing!

Aww, that was cute and sad at the same time. Poor Sulley and Randy, if only they'd had the confidence to be themselves.
